论文摘要
一旦出现了一阶电子相变，未来的引力波观测可能会对希格斯电位的新物理校正敏感。我们研究了SMEFT尺寸六算子对HIGGS潜力的影响，其中考虑了三种类型的效果：（i）SMEFT树水平对$φ^6 $操作员的影响，（ii）SMEFT树水平对HIGGS领域的波浪函数的效应，以及（iii）SMEFT Top-Quark Top-Quark One-loop级别的效应。通过进行Fisher矩阵分析来计算未来重力波观测到这些效应的敏感性。我们发现，一旦一阶电子相变产生，未来的重力波观测可能会对（ii）和（iii）敏感。还讨论了尺寸 - 八$φ^8 $操作员对一阶电动相位过渡的影响。还将未来重力波观测的敏感性与未来对撞机实验的敏感性进行了比较。
Future gravitational wave observations are potentially sensitive to new physics corrections to the Higgs potential once the first-order electroweak phase transition arises. We study the SMEFT dimension-six operator effects on the Higgs potential, where three types of effects are taken into account: (i) SMEFT tree level effect on $φ^6$ operator, (ii) SMEFT tree level effect on the wave function renormalization of the Higgs field, and (iii) SMEFT top-quark one-loop level effect. The sensitivity of future gravitational wave observations to these effects is numerically calculated by performing a Fisher matrix analysis. We find that the future gravitational wave observations can be sensitive to (ii) and (iii) once the first-order electroweak phase transition arises from (i). The dimension-eight $φ^8$ operator effects on the first-order electroweak phase transition are also discussed. The sensitivities of the future gravitational wave observations are also compared with those of future collider experiments.
